Very beautiful your cats; some might think that having a cat is tiring; but in reality these little friends fill our souls. At home we had 7 cats and unfortunately 3 of them died tragically, one disappeared and two were run over because they run away. Actually as you say, without them the house feels empty.
oh wow! you also have quite a bit of cats. It's unfortunate that some of them were run over. I think cats really make the house lively.
